I bought a black straw "cowboy"-style hat when I was in Montana, so I would have something to shade my face and contain my hair. It worked especially well when I wore a topknot or had my hair loose, not so well with a bun off the center back, which interfered with the hat's proper location on my head.

Forgot it there.

Actually, I only bought it for the trip when I realized I was going to be walking outside a lot, and the sun is very bright there. Where I live, we don't have much use for straw hats most of the year, so I'm going to need to be getting or making some warm hats really soon.

I don't wear hats other than during the winter.  When the winds blow and/or the temps get low enough that I need a head covering, I wear a hood/scarf.  I made a number of these last winter.  They are fleece on the outside and a smooth satin-like fabric on the inside.  I can wear this over a bun or braids without messing up my hair and still keep my ears and head warm.

I have never heard of a snood, what is that? *curious* 

I do not have much luck wearing hats, I guess I don't have a "hat-head".  I love when girls can just throw on a baseball cap to cover their hear, and it looks so cute, but not on my head!  If I am having a dirty hair day and need to quick cover up, I usually go with the bandana to cover the entire top of my head, and then do low pig tales, or a pony tale in the back.  I must wash my hair every day or I get very greasy looking, and my hair will begin to separate and look terrible!  But on my day off when I don't feel like showering first thing, the do-rag does just fine, and I can go out and walk the dog and just look "casual", not dirty!  In the winter when it gets very cold here, I will wear a winter hat, and I have a favorite woolen over-sized scarf that I bought up in Boston that I will put over my head like a hood, and then wrap around my neck and face if necessary.  Speaking of winter, I'm really not looking forward to it...

A snood is also called a caul:

These things are comfy 

I never have success with hats. I usually wear my hair in a high ponytail and the hat hits in the wrong spot making it look like I have a big lump on my head.    

During the summer I wear a sun visor. the visor does nothing to protect my hair but at least it sheilds my face from the sun which can get hot here in California. 8)

Thanks Anais Satin, so that's what a snood is!  I've seen them before but did not know what they were called.  This opens up a whole new dimension for me, I never even considered one of those for myself until now, hmmmmmmmmm............................
